Flo Masters For 94 Ls400

[lexfourcam]

i got flo masters installed recently on my ls400 it sounds good at a low rpm but when u really smash the gas u dont really hear the exhaust u hear the engine ive been told i have a slight exhaust header leak but would that really make all the difference?

[jcrome04]

Leaks can make a HUGE difference. Did you do the entire exhaust system, or just replace the two end mufflers?

Any audio/video???? :)

[lexfourcam]

ive just done the 2 rear mufflers and ive got custom piping from the center muffler back to them it was all done rite by this custom exhaust shop i was thinkin about headers but they cost too much. ive heard of cuttin the 2 cats on the headers off but would that really make a difference?

[jcrome04]

You'd get some more sound out of it... Do they do emissions over there?

[lexfourcam]

i live in FL but i dont think so. i kno its illegal but i kno quite a few ppl that have done it and i was just wondering if that would have any affect on it i guess i'll get 2 new exhaust manifold gaskets and cut those stupid cats off while i replace em

[jcrome04]

Yeah the only thing that happens when you take out the cats is

1. You'll get more sound

2. You'll fail emissions

But if you're in a state where they don't do emissions it doesn't matter.

Don't forget to get some audio/video for us!! :D

Check the manifold. If you've got a leak you'll hear the valves.

[lexfourcam]

yea im gonna get that replaced but the cars also makin another noise the engine makes a tapping sound when it idles low ive been told those r the lifters tapping. is that really bad should it b fixed rite away?

[jcrome04]

I think the "tick" is kind of an inherant thing to the LS's v8. or so i've heard.

Not a biggie, just an annoying tick.

[lexfourcam]

oh i see. thanks for all your help i thought there was nothing wrong with it my brother and his friend thats a mechanic thought it was the lifters but it couldnt because it sure did go 145 really easy : ]

[jcrome04]

Haha damn!!

i had my old Lex up to 100mph but I had huge 20"s and stock brakes so I decided to be somewhat responsible and slow the hell down! lol

[lexfourcam]

yea i dont plan on goin that fast again cuz it was pretty *BLEEP*in scary and i realized it when i went passed somebody that was doin the 50mph speed limit

When you put in flowmasters it's a good idea to put in a crossover as close to the headers as possible. Since you have no headers why the flowmasters? Seems redundant.

[lexfourcam]

well it does sound alot better but i just ordered s&s headers that are sposed to give it 35hp. i just got one question exactly how hard is it to get those headers off?

[jcrome04]

I've heard it's a pretty involved process.

[new2mud]

i was thinkin about headers but they cost too much.

The 1st gen LS has very efficient exhaust manifolds--the SC had more restrictive manifolds where headers provided greater benefit.

Adding an X-pipe and free-flowing rear mufflers (like you did) should take care of most of the major restrictions on the LS.

[lexfourcam]

yea so today i went and had my exhaust looked at and they said that its not a header leak its a pipe and there was gas fumes leakin out from the bottom i noticed so i got some glass packs and i got some cherry bomb mufflers i'll get some audio up of it, should sound really sick

[jcrome04]

CANT WAIT!!!!!!!!!!!!! :D
